Hilton Honors is again offering a Status Match. To match your status with Hilton HHonors Silver, Gold or Diamond status, you must provide your Hilton HHonors account number and proof of current tier status with Starwood Preferred Guest, Marriott Rewards, IHG Rewards Club, Hyatt Gold Passport, Choice Privileges, or other hotel loyalty program by June 30, 2016. This time they have a dedicated page where you can submit your request.
You need to show Proof of Status as well as Proof of stay within the last 12 months with other Hotel Loyalty Programs, in order to be matched.
It will take about 10 business days for your upgraded elite status to be reflected in your HHonors account profile. The upgraded status will be valid through March 31, 2018.
